From Viruses to Cybercrime
As Internet and e-mail become an ever-increasing part of our 21st-century lives, the myriad dangers and risks that come with them are increasing too. Make sure you know how to deal with the threats that face us.
From Viruses to Cybercrime
In the past, PCs were mainly under threat from viruses and worms. The main purpose of these programs was to spread; however, some programs were also designed to cause damage to files and PCs. Such malicious software, or “malware”, could be described as ‘cyber vandalism’. In the majority of cases, the goal of viruses and worms was to spread as much as possible, with a high infection rate leading to fame for that program.
But in recent years, the situation has changed drastically.
Today, the biggest threat faced by computers is crimeware. This malicious software is written by cybercriminals with the purpose of making money illegally. Crimeware may take the form of viruses, worms, Trojans or other malicious programs.
Just like burglars break into houses, hackers break into computers. Do you ever wonder how hackers get inside your computer? How can you stop them?
What is a hacker?
The term hacker was once used to describe a clever programmer. Today, it’s applied to those who exploit security vulnerabilities to break into a computer system. You can think of it as electronic burglary. Hackers regularly break into both individual computers and large networks. Once they have access, they may install malicious programs, steal confidential data, or perhaps use compromised computers to distribute spam.
What is a vulnerability?
Today’s computer software is very complex, comprised of thousands of lines of code. Since software is written by humans, it’s hardly surprising that they contain programming mistakes, known as vulnerabilities. These loopholes are used by hackers to break into systems; they are also used by authors of malicious code to launch their programs automatically on your computer.
How do I protect myself from hackers?
Hackers are like electronic burglars, who use loopholes in your programs – vulnerabilities – to break into your computer system. You can protect yourself from hackers by using a firewall. A firewall program, which often comes as part of an anti-virus software package, protects a PC by detecting potential intruders and making the PC invisible to hackers.
